Thousands of inorganic and organic chemicals and their metabolites enter the biosphere daily as a direct result of human activities.
Many of these chemicals have serious consequences on sensitive species of natural resources, crops, livestock, and public health.
The most hazardous of these were identified by a panel of environmental specialists from the U.
S.
Fish and Wildlife Service; these chemicals are the focus of this encyclopedia.
For each priority group of chemicals, information is presented on sources, uses, physical and chemical properties, tissue concentrations in field collections and their significance, lethal and sublethal effects under controlled conditions.
This includes effects on survival, growth, reproduction, metabolism, carcinogenicity, teratogenicity, and mutagenicity - and proposed regulatory criteria for the protection of sensitive natural resources, crops, livestock, and human health.
